Evaluation of energy-saving effect during the installing process of automated heating stations in educational institutions

Abstract

Abstract The aim of the work is to assess the energy-saving effect after the installation of automated individual heat points that carry out weather regulation of the heating load. The analysis was carried out for 18 educational institutions of the Belgorod region, in which energy service contracts were implemented in 2016. The data of the actual monthly consumption of heat energy during the basic heating season before the implementation of energy-saving measures and data of daily accounting of heat consumption during the two heating seasons after the installation of automated individual heat points were used. The average unit savings for all institutions was 14 per cent. It is established that the greatest value of economy, 20-30%, provides decrease in temperature in buildings to optimum level. Elimination of “overflows” in the autumn-spring period allows to save 5-10% of thermal energy. The decrease in temperature on non-working days is characterized by a small amount of savings, not more than 3%, or its absence.
